RE: [MW:4194] Welding of Aluminum plate grade 6082 T

we are using a normal bend test method where we do the same on carbon steel.
the fracture is in the HAZ. so, even when you start bending it, it is broken straightway.
 
i would like to get more info about the changing of bend test methods.
 
best regards,

> If fracture takes place in the heat affected zone and you are using three-point bend testing: we have also had some experience with this in the past. Due to the severely softened zones in the HAZ, all deformation tends to take place in the HAZ. This produces a virtual former diameter which is significantly smaller than the actual former diameter. A solution to that might be to change your bend testing method (in agreement with your client, of course). Please let me know if you require more details about this.
